Abstract

A method for depth perception based on vehicle headlights arranged on both sides of a vehicle includes projecting, by a first vehicle headlight, a first characteristic light pattern onto a projection surface and projecting, by a second vehicle headlight, a second characteristic light pattern. The method also includes capturing an image of the projection surface using an image capturing unit of the vehicle, calculating a frequency representation of the first and second characteristic light patterns in the captured image, and calculating, by evaluating frequency components in the frequency representation of the first and second characteristic light patterns, a coverage coefficient which is correlated with the degree of mutual covering of the first and second characteristic light patterns. The method further includes comparing the coverage coefficient with a coverage threshold value and displacing the first and second characteristic light patterns relative to one another if there is insufficient mutual covering.
